三江平原泥炭中营养元素垂直分布特征

摘要/Abstract

摘要： 采用冬季采样、现场分层的方法,系统地研究了三江平原河床河漫滩型泥炭地和谷底洼地型泥炭地中常量营养元素N、P、Mg、Ca、Fe和微量营养元素Cu、Zn、Mn、B的垂直分布特征.结果表明,总N在泥炭表层富集,总P在草根层富集,其含量随剖面深度的增加而降低,Zn、Mn、B、Mg、Fe表现出草根层富集和淤泥质亚粘土潜育层急剧积累,Ca元素含量在剖面各层次中分布较均匀.某些营养元素间具有显著的相关性.

Abstract: Based on the methods of sampling in winter and dividing soil layer on the site, the vertical distribution character of normal amount nutrient elements N, P, Mg, Ca, Fe and nutrient trace elements Cu, Zn, Mn, B in peat of river bed-flood land and valley depression land in the Sanjiang Plain was studied systematically. The results showed that TN was accumulated in surface layer of peat, and TP was accumulated in root layer. The contents of TN and TP were decreased with the section depth increasing. Zn, Mn, B, Mg and Fe were gathered in root layer and accumulated sharply in gley horizon of silt sub-clay, and the content of Ca was regular relatively in each layer of section. There were close correlations among some nutrient elements in peat section.
